title: Psychopathic traits from the perspective of self and informant reports: is there evidence for a lack of insight?
abstract: It has been suggested that psychopathic individuals are incapable of providing valid reports on their own personality functioning because they are either unwilling (i.e., pathologically lie) or unable (i.e. lack insight) to do so. Despite the long-standing nature of this suggestion, almost no empirical research exists on this topic. In the current study, the authors examined the issue of psychopathy and insight by testing self and informant convergence and mean level differences across 3 indices of psychopathy in a community sample (N=64). Self- and informant-report psychopathy scores were also examined in relation to self and informant reports on traits from the Five-Factor Model (FFM). Convergence was strong across the 3 psychopathy indices and their respective factors (i.e., median r=.64), and there was only modest evidence that individuals rated themselves as less psychopathic than did informants. In addition, the same FFM domains-low Agreeableness and Conscientiousness-characterized individuals with psychopathic traits regardless of reporter. Psychopathic individuals appear capable of reporting accurately on psychopathic traits when there are no direct consequences to accurate reporting (i.e., sentencing). It may be that the lack of concern for the consequences of these traits has been mistaken for a lack of insight into them.
